cannot see data in SAP.Web.UI.Controls.Table

Hi,I have created a portal project and dragged a sap table into the design area. then i call a webservice and bind the resulting dataset to the table. the dataset seems to bind, since i can see there are the right number of pages in the table, but i cannot see any of the data. all the rows are blank. am i treating the ascx file correctly? i deploy and browse to test it.
